Auxiliary Water Pump (Bosch-OEM) for 2.7t (B5 S4-RS4 All, 00-02 A6-Allroad)

NOTE: For B5 S4 All and 00-02 A6 and Allroad only with the standard rectangular electrical connector. In 2003 the A6 and Allroad switched to a more irregular shaped connector with rounded edges. If you have a 2003 to 2004 A6 or a 2003 to 2005 Allroad make sure you get the other pump on this product page.

This is the auxiliary water pump which resides underneath the intake manifold of the 2.7T engine. The factory unit commonly leaks and this OEM Bosch replacement has an upgraded sealing flange to prevent leaks in that common place of failure.

When replacing this pump you have to lift up, or remove the intake manifold so this is a great time to upgrade with intake spacers to keep your intake temps a little lower and add some performance. Check our engine parts section for these.
